Was he just a one night stand?

I met up with a guy thinking it was just a one night stand. But we ended up talking and watching tv (hanging out) for like 3 hours before we even did that. He seemed a little disconnected during but thats kind of the person he is (gets distracted easily) After it was over it was a little awkward and silent for about 20 min. Before I left he asked how to spell my last name so he could save it in his phone, then he said he would see me later. I texted him something funny later that morning and he replied with "lhh" and that was the end of the convo.
